This application is a continuation application from Ser. No. 09/169,871,filed Oct. 12, 1998 now abandoned, which is based upon provisional U.S.patent application Ser. No. 60/062,559, filed Oct. 21, 1997, andprovisional U.S. patent application Ser. No. 60/094,803, filed Jul. 31,1998, the entire contents of which are incorporated by reference.

BACKGROUND OF THE INVENTION

Light bars or emergency lights of the type used on emergency vehiclessuch as fire trucks, police cars, and ambulances, utilize warning signallights to produce a variety of light signals. These light signalsinvolve the use of various colors and patterns. Generally, these warningsignal lights consist of revolving and oscillating lamps havingreflective back support members and colored filters as depicted in U.S.Pat. No. 5,091,828.

Many problems exist with the known methods for producing warning lightsignals. One particular problem with known light bars is their relianceon mechanical components to revolve or oscillate the lamps to producethe desired light signal. Additionally, these components increase thesize of the light bar or emergency lights which adversely affect itsdrag characteristics. Moreover, there is an increased likelihood that abreakdown will occur requiring the repair or replacement of thedefective component.

The most common light sources being used in light bars or emergencylights include halogen lamps or gaseous discharge xenon lamps. Theselamps emanate large amounts of heat which is difficult to dissipate fromthe sealed light bar or emergency light and may damage the electroniccircuitry contained therein. In addition, these lamps consume largeamounts of current requiring a large power supply or large battery orelectrical source. These lamps also generate substantial electromagneticemissions which may interfere with radio communications. Finally, theselamps, which are not rugged, have relatively short life spansnecessitating frequent replacement.

Another problem with the known warning signal lights is their use offilters to produce the desired color. This filtering technique producesmore heat that must be dissipated. Moreover, changing the color of alight source requires the physical removal of the filter from the lightbar or emergency light and the insertion of a new filter. Furthermore,filters fade or flake making them unable to consistently produce thedesired color.

These problems associated with traditional signaling lamps areexacerbated by the fact that creating multiple light signals requiresmultiple signaling lamps. Further, there is little flexibility inmodifying the light signal created by a lamp. For example, changing astationary lamp into one that rotates or oscillates would require asubstantial modification to the light bar which may not be possible.

In view of the above, there is a need for a warning signal light that:(1) is capable of producing multiple light signals; (2) producing theappearance of a revolving or oscillating light signal without relyingupon mechanical components; (3) generates little heat; (4) usessubstantially less electric current; (5) produces significantly lessoramounts of electromagnetic emissions; (6) is rugged and has a long lifespan; and (7) produces a truer light output color without the use offilters.

Light bar 70 includes base 72, mounting means74, cover 82, and warning signal lights 10. Also included in light bar70 are gyrators 90 used to impart motion to warning signal lights 10.

Referring to FIGS. 3 and 9, warning signal light 10 comprises lightsupport 12, light sources 30, controller 50 (shown in FIG. 11), andconnecting portion 40 for attaching the warning signal light to lightbar 70 or gyrator 90. The warning signal light 10 operates to create awarning signal for use by an emergency vehicle by selectively activatinglight sources 30 using controller 50.

Light sources 30 are preferably light emitting diodes (LED's) and aregenerally arranged in aligned columns 32 and rows 34 as shown in FIGS. 7and 9. Each of the light emitting diodes (LED's) may have shoulderportion 38 adjacent LED support 12 and dome 36. LED's 30 are situated tobe in electric communication with controller 50 and a power supply, abattery, or power source. The use of light emitting diodes (LED's)instead of the traditional halogen or gaseous discharge xenon lampsresults in a reduction of heat generation, current draw, andelectromagnetic emissions, while increasing lamp life and producing amore true output light color.

Controller 50, is used to selectively activate columns 32, rows 34, orindividual LED's 30, to create a constant light signal, a strobe lightsignal, a flashing light signal, the illusion of a rotating or anoscillating light signal, a reverse character message, or images such asarrows. FIG. 11 shows an embodiment of controller 50 capable ofselectively activating columns 32, rows 34 or individual LED's 30.Controller 50 generally comprises microprocessor 52 and circuitry 53 andis preferably contained within, attached to, or an element of, LEDsupport 12. It is envisioned that controller 50 be programmed by anexternal controller and powered through cable R.

In a preferred embodiment, controller 50 generally comprises circuitboard 54 having microprocessor 52 attached to a low voltage powersupply, battery, or electrical source 56. Microprocessor 52 isconfigured through circuitry 53 to selectively activate columns of LED's30. Transistors Q9 and Q10 are in electronic communication withmicroprocessor 52, power supply, battery, or electrical source 56, andtheir respective columns 32.9 and 32.10 of LED's 30. Columns 32 of LED's30 are connected to transistors Q1-Q8, which are in turn connected tomicroprocessor 52 through resistors R1-R8. Microprocessor 52 is capableof selectively activating transistors Q1-Q8 to allow current flowingthrough transistors Q9 and Q-10 to activate the selected column 32 ofLED's 30. This circuit is capable of producing a revolving, oscillating,or flashing light signal.

In the preferred embodiment, a rotating or oscillating light signal ispreferably established by the sequential illumination of entire columns32 of LED's 30 turning a desired number of columns on and thensequentially illuminating one additional column 32 while turning anothercolumn 32 off. Alternatively, the rotating or oscillating light signalmay be created by selectively activating columns 32 of LED's 30.

20) return to step 1).

A clockwise revolving light signal is created by performing steps 1-19in descending order then repeating the steps. An oscillating lightsignal is created by performing: (a) steps 7 through 16 in ascendingorder; (b) steps 7 through 16 in descending order; and (c) repeating (a)and (b).

A second embodiment of controller 50 provides a means for activatingLED's 30 individually to allow for greater flexibility in the type oflight signal created. This embodiment of the invention is capable ofdisplaying information in different colors or patterns. Depending on thesize of the display, it may be necessary to scroll the symbols orcharacters across the display to accommodate for a larger visualappearance. It is envisioned that the mirror image of patterns, symbols,or characters could be displayed making the message easily readable bydrivers viewing it in their rear view mirror. It is also envisioned thatthis embodiment of the invention could display arrows indicating adirection the viewer is to travel or other images as shown in FIG. 2. Inaddition, combinations of signaling lights, direction arrows, and otherinformation carrying signals or images, could be displayedsimultaneously by the invention.

LED support 12 is envisioned to have several embodiments. Oneembodiment, shown in FIG. 9, consists of a panel 14 having front 16,back 18, top 20, 5 bottom 22 and sides 24. LED's 30 are arranged onfront 16, with domes 36 extending therefrom, in columns 32 and rows 34.LED's 30 are in electric communication with controller 50 which may becontained or sealed within LED support 12 to provide protection from theelements. In addition, panel 14 may be circuit board 54 of controller50.

Another embodiment of warning signal light 10 is depicted in FIG. 10.Here, the backs 18 of two panels 14 are attached together to allow for alight signal to be produced on two sides. The two panels form LEDsupport 12. Alternatively, it is envisioned that a single panel 14having LED's arranged about front 16 and back 18 could be used as well.

FIGS. 6 and 8 show further embodiments of warning signal light 10. InFIG. 8, panels 14 are used to form an LED support 12 shaped as a squarecylinder. FIG. 6 shows panels 14 connected to form a triangularcylinder. In both embodiments, LED's 30 are arranged about the fronts 16of the panels 14. It is further envisioned that panels 14 may beintegral to each other.

Yet another embodiment of warning signal light 10, consists of aflexible panel 14 and controller 50 to allow LED support 12 to be formedinto various shapes. FIG. 5 shows LED support 12 formed into a circularcylinder. Further variations include the use of flexible panels 14 toform other shapes such as semicircles (FIG. 12) or to simply conform toa surface of an emergency vehicle (FIGS. 13 and 14). This embodiment isparticularly useful for undercover vehicles which generally position thewarning signal lights inside the vehicle. For example, panel 14 could beattached to the front, rear, or side window of an undercover police car(FIG. 15).

It should be noted that numerous other shapes could be formed frompanels 14 including those formed from combinations of flat, curved, andflexible panels at the preference of an individual.

In each of the embodiments discussed above, the array of LED's 30 maycomprise the same or differently colored LED's. Generally, each columnmay consist of a series of differently colored LED's. Controller 50 canbe configured to select the color LED to utilize in forming the lightsignal. Accordingly, the user may select that a blue, red, white,yellow, green, amber, or combination thereof be used as the color oflight signal.

It is also envisioned that the controller 50 may control warning signallights 10 having multiple sides (FIGS. 5, 6, 8, and 10) such that eachside is capable of producing light signals that are independent fromthose produced by the other sides. For example, the square cylinderwarning signal light shown in FIG. 8 may produce a red revolving lighton first side 15.1, while second side 15.2 is simultaneously producing ablue oscillating light, while third side 15.3 is producing a stationarywhite light, and while fourth side 15.4 is producing a white strobelight.

Another embodiment of warning signal light 10 is depicted in FIGS. 1 and2 as light bar 70 which extends from driver side 100 to passenger side102 of emergency vehicle 104. Cover 82 protects light bar 70 from theelements. Each side of light bar 70 may have LED's 30 to produce lightsignals on each side of emergency vehicle 104. Furthermore, controller50 is used to create multiple light signals on each side of light bar70. For example, controller 50 could create a revolving blue lightpositioned at front passenger side 102 of light bar 70, oscillatingwhite lights positioned at front driver side 100, and yellow arrowstherebetween. Additional light signals may be produced out the back andsides of light bar 70. It is further envisioned that light bar 70 mayconsist of a single large array of LED's 30 across each side (notshown). This embodiment provides the largest display and, therefore, isbest suited to display combinations of warning lights and images.

Mechanical rotation and oscillation of warning signal lights 10 aboutaxis A is possible by way of attachment to gyrator 90 depicted in FIG.3. Gyrator 90 mounted to light bar 70, generally comprises electricmotors 96 having cables 97. Gyrator 90 is configured to receiveconnecting portion 40 of warning signal light 10. Cable 97 connects to apower supply and either an external controller or controller 50.

Gyrator 90 may be capable of rotating or oscillating warning signallight 10 about a single or dual axis of rotation A. FIG. 3 shows gyrator90 configured to rotate or oscillate warning signal light 10 about avertical axis A by way of motor 96.1 and oscillate warning signal light10 about a horizontal axis A by way of motor 96.2. Rotation oroscillation of warning signal light 10 about vertical axis A isaccomplished through direct attachment of connecting portion to motor96.1. Oscillation of warning signal light 10 about horizontal axis A isaccomplished by attaching swivel arm 99 to bracket 99.1 and post 99.2which is mounted to motor 96.2.

Alternative methods for imparting rotation or oscillation of warningsignal light 10 can be accomplished through the use of electric motors,toothed gears, and worm gears. In addition, maintaining an electroniccommunication between a power supply and an external controller with arevolving or oscillating warning signal light 10 can be accomplishedusing brushes or other means without sacrificing the operation of thewarning signal light 10.

In another embodiment as depicted in FIGS. 13 and 14, emergency vehicle104 may include a front or rear windshield 106. The front or rearwindshield 106 is generally angularly offset with respect to the vehicleat an approximate angle of 45 degrees. In this embodiment, the mountingof a panel 14 of light sources 30 in flush contact with the interior ofa front or rear windshield 106 occurs through the use of angular offsets108 for the light sources 30 such that light emitted from the lightsources 30 occur at a horizontal visual line (V) which is substantiallyparallel to the plane of a vehicle and not at an approximate angle of 45degrees upward which corresponds to the angle of incident for the frontor rear windshield 106.

In this embodiment, the ease of visualization of the light source 30 issignificantly enhanced by the downward angular offsets 108 whichposition the light sources 30 along parallel visual lines of sight (V).LED supports 12 or panels 14 may then be positioned in any desiredlocation within the interior of a vehicle in flush contact or proximateto the front or rear windshield 106. A suitable cable 97 is naturallyrequired to provide electrical power for illumination of the lightsources 30. It should be noted that the angle of incidence for theangular offsets 108 may vary considerably dependent upon the make ormodel for the vehicle to include the warning signal lights 10.

It should be further noted that the warning signal light 10 may be usedwith an automobile, motorcycle, snowmobile, personal watercraft, boat,truck, fire vehicle, helicopter, and/or any other type of vehiclereceptive to the use of warning signal lights 10. It should be furthernoted that LED support 12 or panel 14 may be mounted to the interior topdashboard of a vehicle proximate to the front windshield 106 or to theinterior top rear dashboard proximate to the rear windshield 106 of avehicle.

Mounting of a light support 12 or panel 14 to either the front or reardashboards may minimize the necessity for inclusion of angular offset108 for the light sources 30. It should be further noted that LEDsupports 12 or panels 14 may be releasably affixed to the interior ofthe front or rear windshields 106 via the use of suction cups,hook-and-loop fabric material such as Velcro®, and/or any otherreleasable affixation mechanism at the preference of an individual. Anindividual may then adjust and reposition the location of the lightsupport 12 or panels 14 within the interior of a vehicle as desired formaximization of visualization of the warning signal lights 10.

In another alternative embodiment as depicted in FIG. 15, warning signallight 10 may function as a remote, revolving, or stationary beacon. Inthis embodiment, LED support 12 or panel 14 is preferably releasablyconnected to a transportable support 120 via the use of a bracket. Thetransportable support 120 may be a tripod having telescoping legs or maybe any other type of support as preferred by an individual. In thisembodiment, LED support 12 or panel 14 is electrically connected to anelongate electrical extension cable 97 which may include any desiredadapter for electrical communication with the electrical system of avehicle. The remote light support 12 or panel 14 may also includeplug-in adapters for electrical connection to any desired electricalpower source other than a vehicle as is available.

The transportable support 120 may also include gyrator 90 as earlierdescribed to provide a desired rotational or oscillatory motion forwarning signal light 10. A controller 50 having a microprocessor 52 mayalso be integral to or in electrical communication with LED's 30 for theprovision of multi-colored lights, flashing, or moving characters asdesired by an individual. In this embodiment, the warning signal light10 may be physically separated from an emergency vehicle any desireddistance to facilitate or enhance the safety of a potentially dangeroussituation necessitating the use of warning signal lights 10. Inaddition, it should be noted that a series of remote warning signallights 10 may be electrically coupled to each other for any desireddistance to again facilitate the safety of a situation necessitating theuse of warning signal lights 10.

The present invention may be embodied in other specific forms withoutdeparting from the spirit or essential attributes thereof; and it is,therefore, desired that the present embodiment be considered in allrespects as illustrative and not restrictive, reference being made tothe appended claims rather than to the foregoing description to indicatethe scope of the invention.
